Abstract

The invention relates to an improved method of producing double-metal cyanide (DMC) catalysts for the production of polyether polyols by polyaddition of alkylene oxides to starter compounds containing active hydrogen atoms, in which the DMC catalyst dispersion is produced using a mixing nozzle, preferably a jet disperser. The DMC catalysts produced in this way have an increased activity in polyether polyol production, reduced particle size and narrower particle size distribution.
